It covers the four species mentioned and it appears that Hohenbuehelia carbonaria is easily separated by having metuloid cheilocystidia (which I think this observation has). There are descriptions for the other three but not for H. carbonaria, so I’m not sure how it compares in any other respect.

particularly the nematophagy. It seems odd to think of a mushroom being predatory.

I have ordered Cheryl Grgurinovic’s book and am waiting patiently for it to arrive – expected delays :( It includes descriptions for each of the species you mentioned. Hopefully it will shed some light on this observation.

It’s probably not culmicola then. But I found four rare species that I beleive are originally described from Australia, but haven’t been able to find pictures or descriptions of any of them (bingarra, clelandii, karrara and carbonaria).

These were found in an area of reclaimed Eucalypt woodland, growing through the middle of a small mound of moss near base of an Ironbark (E. tricarpa). The myc was somewhat rhizomorphic and growing throughout the soil and dead moss within the clump.
